On topic: by 2 look PLL, what algorithms are you using? If you only know A and U perms, that then you could have 3/4 look PLLs, because you might have to switch corners diagonally, or have a Z or H perm when it comes to the edge switching. For the former, you would have to use an A perm twice, and for the latter, you would need to use a U perm twice.
Practice F2L more: "learn" a few of the cases, then try to work out how to resolve other cases yourself, using the basiuc principles that you learnt before. I found it much easier to "learn" F2L this way.
